Make an Electromagnet
Electrons in motion create a magnetic field. Materials are magnetic when their electrons are all spinning in the same direction. Natural or permanent magnets have their charges lined up in the same direction, while non-magnetic materials do not. However, we can make a metal such as iron magnetic by exposing it to an electrical charge.

DOE Explains...Batteries
Similarly, for batteries to work, electricity must be converted into a chemical potential form before it can be readily stored. Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit.
How to Make a Homopolar Motor | STEM Activity
When the wire touches the top of the battery and the magnet (which is touching the bottom of the battery) at the same time, electrical current flows through the wire. This electrical current passes through the magnetic field created by the magnet. This results in a force that pushes on the wire, causing it to spin around the battery.
7.2: Magnets, Electromagnets and Magnetic Matter
Ferromagnets. Only certain materials, such as iron, cobalt, nickel, and gadolinium, exhibit strong magnetic effects. Such materials are called ferromagnetic, after the Latin word for iron, ferrum.A group of materials made from the alloys of the rare earth elements are also used as strong and permanent magnets; a popular one is neodymium.
